One way to verify the red/white wire that feeds the signal to the signal to the ECU is to measure from the harness pin to gnd (car power off). It will read approx 10k ohms. Combined with the voltage reading from S4 above all the wires can be checked. The oil level sensor wiring harness joins with the turbo sensors and becomes the main engine wire harness that down the exhaust cam and around the back of the block.

I poked around while I was doing my timing chain last night.
absolutely, I didn't check that w/ ohms, just volts, but that sounds spot on - correct!!

Also I noticed when I had the harness unplugged testing wires and turned car to the on position, it started right up but the display read 'Faulty Oil Level Sensor" NOT "low oil level" like mine had previously been saying,
so if you have a bad oil level sensor that has little or no power coming from it, and/or in this case the plug isn't plugged up or worse case, a wiring issue, it would say "faulty oil sensor" not "low oil level" like mine showed, I didn't have a Vag-Com cable or I would of known this a month ago

But regardless, for some reason just that fuse missing didn't cause an electrical issue with it for it to display "faulty sensor", it just never let the display update after I changed oil and sensor and caused the light to stay on no matter what I did... Weird I know basically just froze on there bc it never had a chance to update itself, so basically anyone reading this in the future, very first make sure your fuse is good, then check the sensor, then wiring last, bc as far as costs goes it also goes in that order and I am glad I only spent the $3 I spent on 5 fuses (and only uses 1) still got 4 left :) ... than buying a new wiring harness which I was on the verge of.
